Im wanting a Camera that wil take quick shots of the family, currently have a samsung WB600, but I find that it takes a coupe of seconds at least to capture the shot, not good with children. Ive been looking at the Canon Powershot SX500, Its light to hold got a good zoom and Lithium Battery, which I like and the price is what I was wantng to pay. I just need a reasonable camera that is easy and quick to use. Isthis suitable or is there anything else out there that I should be looking at.
